The second TROPECOS field work in mangroves of Rio de Janeiro (Mamangua and Itacoatiara) 24 May 2025 – 7 June 2026, involved 14 TROPECOS research scientists and students from BOREA, LPG, UFF and UFPA. We measured gas fluxes in mangrove soils and waters, dissolved carbon concentrations and water current in tidal creeks, and high resolution dissolved redox species in sediments using 2D gels.
